Lab-Tech is recognized as the leader in testing for the membrane switch industry. Our lab personnel have played a key role in developing ASTM standards, and providing an independent evaluation of testing procedures needed to enhance the quality and performance of keypads and membrane switch devices. As such, we are often asked to evaluate quality and production processes, help determine causes for test sample failures, and design and perform custom tests. These projects can be performed on either a fixed fee basis or at an hourly rate

A wide variety of electrical tests are performed to determine the various characteristics of a switch or keyboard. Usually, pre and post test inspections/determinations/tests are conducted to verify the basic operational functions of the test samples, to establish baselines for the specific tests involved and to qualify the effects of testing after exposure to mechanical and environmental variables.

Electrical tests we are frequently requested to perform for our customers include, (but are not limited to):

• Contact Resistance
• Circuit Resistance
• Continuity
• Capacitance
• EMI/RFI
• Contact Bounce Time
• Current Carrying Capacity
• Dielectric Withstand Voltage
• Electrical Shorts
• Electro Static Discharge (ESD)
• Insulation Resistance
